massenstoffe
Massenstoffe, also known as mass nouns, are a category of nouns that refer to substances, concepts, or ideas that are not countable. Unlike countable nouns, which can be quantified with numbers (e.g., "three apples"), massenstoffe cannot be counted individually. Instead, they are measured using units of quantity, such as kilograms, liters, or portions.
Examples of massenstoffe include abstract concepts like "love," "happiness," and "time," as well as tangible substances
In German, massenstoffe are often referred to as "Mengenwörter" or "Mengenbegriffe," which translates to "quantity words"
